Goals from Jamie Vardy and Riyad Mahrez consigned Chelsea to another defeat tonight as Leicester City beat them 2-1, despite Loic Remy pulling a late goal back for Jose Mourinho's men - but what can we take away from the game?

Reversal of Fortunes

Leicester and Chelsea and two of the biggest stories of the Premier League season. What sort of odds would you have got at the start of the season for Leicester being top and Chelsea being a point off the drop zone having tasted defeat nine times with Christmas still not here yet? Everyone has been waiting for the Leicester bubble to burst and the Chelsea revival to kick in, but there was little sign of either at the King Power Stadium tonight. And what's more, Leicester's win was no fluke – they looked lively and full of ideas while Chelsea looked lacklustre and out of them.

Ranieri no longer the Tinkerman

Claudio Ranieri was derided for being the tinkerman when in charge of Chelsea, unable to resist constantly chopping and changing his side and thus unable to get the best out of his galaxy of star players. Maybe he's learned his lesson, or maybe it's just that he has less to play with at Leicester, but Ranieri fielded an unchanged for the umpteenth time this season to face his former side. Leaving aside the Capital One Cup, when Ranieri has made changes it has never been more than one or two at a time, and even them not very often, and a settled side seems to be a happy side for the Premier League leaders.

Hazard Injury

To rub salt into the wound, Chelsea fans will be waking up tomorrow morning waiting to hear the news on Eden Hazard's injury. Last season's star man and this season's under-performing enigma went down in a crumpled heap under a challenge from Jamie Vardy early on in the game, and despite insisting he wanted to go back onto the pitch as Pedro stripped off to replace him, Hazard immediately pulled up upon crossing the whitewash again and Pedro's tracksuit was removed once more. Minutes later, the man who put Hazard out of the game put Leicester in front. Football, eh?

Vardy v Costa

Jamie Vardy was presented with a silver plate to commemorate him recently breaking the record for scoring in consecutive Premier League matches before the match, while those in attendance were themselves presented with limited edition packets of Walkers 'Vardy Salted' crisps. He is definitely the man of the moment, and has now scored more league goals this season than Cristiano Ronaldo and Lionel Messi combined. Diego Costa, meanwhile, has one goal in his last 10 and could desperately do with a Vardy-like streak of form. Could one replace the other in the January transfer window?

Chant of the Day

It has often been said that the Premier League lacks atmosphere, especially at much-derided Monday night games, but there was an electric one at the King Power Stadium tonight. It probably helped that Leicester are on an all-time high, and that Chelsea fans have responded to their amazing run on bad form with a gallows humour. One particular exchange midway through the first half was hilarious. Leicester fans started by taunting Chelsea's following that they are 'Going down with the Villa', to which Chelsea responded by telling the home fans that 'Villa's won more than you'. Leicester's immediate retort? 'Vardy's scored more than you'. The Leicester fans also took great delight in signing 'Two-nil, and you're walking home' after it was announced that there was a 10-mile tailback on the M1 southbound.
